All electrical and electronic circuits, from the small ones in our homes to the large ones in industry, need to have circuit protection. This protection guards against too much current flowing in the circuit. Too much current in a circuit can cause serious damage. There are two different methods of protecting a circuit: fuses or circuit breakers. This study unit focuses on fuses.
First, this study unit discusses the need for overcurrent protection in modern industrial circuits. There are many reasons why the system wiring, control circuits, and load devices must be protected. Next, fuse ratings and specifications are covered. This section discusses the selection of the correct type and size of fuse in a system.
The following section focuses on typical fuse holders. There are a wide range of fuse holders, from fuses soldered onto a circuit board to those that are clamped into large disconnect switches. Many problems can occur on a fuse holder. This study unit shows how to address the problem until the fuse holder can be replaced. Finally, the unit ends with a discussion of how to safely test and replace fuses in their fuse holders.

Industrial Circuit Breakers

Course #: 086077
Duration: 5 hours
What Students Learn: Preview
As an electrician, one of the most common devices you will see is a overcurrent protection device (OCD). This may be a fuse or a circuit breaker, and every industrial cabinet will usually contain at least one OCD.
The Industrial Fuses study unit covered the various types of fuses. Here the second kind of protective device, the circuit breaker will be examined.
Most people are familiar with the molded-case circuit breakers used in our homes. The home load center will normally contain a main circuit breaker that protects the entire load center for the home, and smaller circuit breakers that protect the various branch circuits.
An industrial control panel is not much different from a home's load center. A large circuit breaker or fuse system is usually located at the main disconnect that supplies the control panel. Each circuit will then contain a smaller circuit breaker or fuse system to protect the branch circuits inside and outside the panel.
This study unit will look at the types of circuit breakers that are commonly used in industry; how they are designed and how they work. We will also look at typical branch circuits for single-phase and three-phase loads. Finally, the study unit will discuss ground fault circuit breakers and outlets, and how to safely work with circuit breakers.

Plugs, Receptacles, and Lampholders

Course #: 086078

Course #: 086079
Duration: 5 hours
What Students Learn: Preview
In the maze of wiring, controls, and equipment in most industrial locations, switches are among the most overlooked devices. Yet switches can cause the most problems when they do not work properly. There are many kinds of switches. When troubleshooting, some can be diagnosed simply by looking at their contacts or actuators. But many more switches consist of intricate, sometimes solid-state circuitry, and use component properties such as inductance, capacitance, and magnetism.
These types of switches are found in the basic electrical circuits and in the control rooms of industrial facilities. They also are used in the regulation of such process-line variables as flow, level, temperature, and pressure.

Industrial Relay Ladder Logic

Course #: 086080
Duration: 5 hours
What Students Learn: Preview
Control circuitry in industrial applications is the brain behind the brawn of motorized power. Motors require one element to perform the work they are designed to do: power. How they get the power is not a concern of the motor, but it is a major concern to the developers of control systems.
Industries, especially those involving sequential operations such as mills, refineries, chemical plants, manufacturing conveyor systems, and any of the processes that require certain events to happen at certain times, require well-designed control systems.
To properly provide sequential operation of these events, a control system designer must start with what is referred to as logic, or sequential events. A ladder diagram is the main tool used by control systems designers to design a control system that causes certain events to happen at certain times.
Once the design is developed, it is up to the electrician or technician to install the system and, later, to maintain it.

Industrial Relays, Contractors, and Solenoids

Course #: 086081
Duration: 5 hours
What Students Learn: Preview
In the Industrial Relay Ladder Logic study unit, we learned that an electromagnetic relay is an electromechanical switch made up of an electromagnet and a set or sets of contacts.
An electromagnet is created by passing electrical current through a wire, causing a magnetic field to form around the outside of the wire. A ferrous metal, which is a metal that contains iron and can be magnetized, will be pulled toward the magnetic field being emitted by the energized coil. If the ferrous metal is shaped into a rod or plunger and is inserted in the middle of the coil, the magnetic field will pull it into the coil's core, and the rod or plunger will try to align itself in the center of the field. If the bar or plunger is mechanically connected to a contact bar, the device is a relay, starter, or contactor. If the plunger in a coil is mechanically connected to a valve or other operating mechanism, the device is a solenoid.
The magnetic field will pull the contact or mechanical device with it, and cause a movable contact to either make contact or break contact with a stationary contact (in the case of a relay), or cause a mechanical action (in the case of a solenoid).
This study unit will delve deeper into the various types of industrial control relays, magnetic starters, contactors, and solenoids, covering their operating principles, construction, components, and applications.

Measurements Trainer

Course #: XK-100
Duration: 0 hours
What Students Learn: The XK-100 Measurements Trainer is a completely assembled, line-operated trainer designed for conducting hands-on experiments on basic electrical and electronic components and circuits. The trainer includes a basic meter with scales calibrated in ohms, milliamps, and AC and DC volts. In addition to a variable low-voltage power supply, the unit also contains a variable bias-voltage supply. For ease in setting up experiments, the Trainer has a general-purpose solderless connector block. A speaker produces an audible output for working with audio frequency. A variable audio-frequency generator in the Trainer can be used to test reactive components and make resonant frequency measurements.
